' To all whom it may concern:

. Be it known thet I, Munitio- Cvsisounn, a citizen of the United States, residing at Merchant-ville, in the county of Camden and State of New Jersey, have invented :in Improvenient in Valves for Heating Apparatus, of which the following is a specification.

My invention reletes to'vslves which are provided with s plurality of ports or pessegewsys of different sizes and may be operetedto open any desired port to provide a thoroughfare of variable but determinate size.

My valve is particnlai ly adopted-tor use, to control theflow oi steam into radiator or heater so that exactly the desired opening or inlet may beprovided.

More particularly it is the object of my invention to provide a valve of this general chsmcter-Which'shall be simple in construction and easy to operate, and which shell not be subject to leakage. Where nice edjustment of the inlet is desired as, for example, in those systems of steam basting Where a modulation. of temperature is ob tsined by the regulation of the inlet valve, it is essential that leakage-of steeni through the valve body around or outside of the opened port should beprevented. and this result is sccomplished'by the present improvements.

Fig. 2 is a'vertioolsectionel view of the valve; Fig. 3 is a plan View; Fig. 4 is s horizontal section of the valve-cage taken in the line A-A of Fig. 2; Fig. 5 is a plan view of the detached valve plate; and Fig. 6 is a plan view of the pointer arresting spring which may be used.

(Z is o cage Whichis inserted in the valve body. and carries a horizontal partition or diaphragm e which forms the true dividing wall between the inlet and outlet and contsinsen opening f' Which constitutes valve controlled thoroughfare or passage way.

Will an opening in through. which the steam passes from the valve inlet to the opening f.

n is the movable valve-piece which consists of a flat plate arranged in contact With the diaphragm c; it is rotatable, and is Bre vided with a plurality oifiopenings 0, 0 0, 7O 0, difi'ering in and arranged so that any one maybe brought into register with the large opening j in the diaphragm c. As

"shown the piste 72, is arranged below the diaphragm c and carriesa central post 0 by means of which it is rotated. This port extends up through the diaphragm, and is operetively connected With it rotary stud p extending through the top It and operated by the handle 7. A spring; 8 between the 0 valve plots n and the thiinble of the esge msinteins the plots in contact with the diephrsgni e. The pressure of the entering steam on the lowe face of the plate 11 also forces its o t the diaphragm; and thus leakage is prevented and only so much steam enters the valve-body as passes through the opening in the series o &c. which is in register with the opening In the construction shown, the end of the 9 post 0 is squared and fits a complementary socket p on the stud gt, A spring t between the diaphragm e and th s socket p maintains the socket flange p in c ntact with the inner face of the cage top it and prevents leakage. The operating handle 'r'may be providedwith a pointer 1 to indicate by numerals-or suitable marks on the top of the valve, the extent oi? movement of thevslve' plate at and which ofthe openings 0 0 8:6. is in re'gis ice ten witli t-he opening f. By means of this L as may be turned to shot the valve hy closin' i 'ng f t" openthe. valve to the e: by ging the proper o z'c. in ms the valve-body arranged to determine the proper positions of the handle when the respective openings o etc. are in register with the opening 7 and thus to prevent the partial openinp or said openings 0', o the.

ln Fig. l the valve is shown applied to the steam inlet i oil? a radiator w and receiving; steam 'l'roin the steam supply pipe it". The quantity ol steam admitted to the radiator controlled by the movement ot the valve plate a by the handle 1' to open one oi the ports 0", 0 &c.. The discharge outlet i" is shown provided with a valve m (which is preferably automatic) discharging to the rc turn pipe w. this constriu-tion is that leakage of steam through the valve 'et'ented; the (plan tity of steam admitted to the radiator is 6011* trolled absolutely by the 16 of the port ol the series 0", 0 the. which is opened, and is not augmented by steam admitted by leakage. The pressure oil the steam acting, in addition to the spring 5, on the plate 1:. maintains it in steam tight contact with the diaphragn'i c, and takes up the ordinary wear resulting lroin the inovemei'it of the plate.

in the construction shown the distance be tween adjacent openings 5;, 0, etc. than the diameter or the opening f. From this it results that: before any opening in the plate npasses wholly from under the opening 7", the next opening in the series in said plate will be brought into partial. register with said openine'. This enables the size of the thoroughfare to be graduated between the limits alloided by the diameter of the openings 0, 0*, are. and prevents the total closing of the opening; or its reduction to an undesirable minimum in intermediate position while the plate u is being turned. The i'lan 'e p maintained by the action. of the sprin z in contact; with top of the valve .IL prevcn the lealtr 'e oi steam without requirinn ex- :ve tie'ht between the stud p and its lt will a. o be noted that with the articular construction of the cage shown, all of the part-5 are contained in and carried by it, and may be applied to a standard valve-body of the character shown, by Sllll ply removing the cap and. the contained valve devices, and screwing inthe cage. \Vhile this is a. particular advantage in some cases, .i do not mean to limit. my invention to this particular construction.
